I created a class CMyClass whose CTor takes a UCHAR as argument. That argument can have the values of various enums (all guaranteed to fit into a UCHAR). I need to convert these values to UCHAR because of a library function demanding its parameter as that type. I have to create a lot of those message objects and to save typing effort I ...
E.g. Integer to Hexa, Integer to Octal Integer to binary and so on.... and vice versa ...
I'm loading a Bitmap from a jpg file. If the image is not 24bit RGB, I'd like to convert it. The conversion should be fairly fast. The images I'm loading are up to huge (9000*9000 pixel with a compressed size of 40-50MB). How can this be done? Btw: I don't want to use any external libraries if possible. But if you know of an open sourc...

Basically I have a NSString the just contain 1 character for example the letter D How do I take that 1 character NSString and assign it to a variable of char So I have... char mychar; NSString *myMode = [[NSString alloc] initWithFo...
Hi, I've done some simple string -> DateTime conversions before using DateTime.ParseExact(), but I have a string that I can't seem to get parsed properly. I'm probably doing something very obvious wrong but I just can't see what it is. The code is as follows: string date = "Tue Jun 23, 2009 2:23 pm"; DateTime lastupdate = DateTime.Par...
I have a string in the format: 'nn.nnnnn' in Python, and I'd like to convert it to an integer. Direct conversion fails: >>> s = '23.45678' >>> i = int(s) Traceback (most recent call last): File "<stdin>", line 1, in <module> ValueError: invalid literal for int() with base 10: '23.45678' I can convert it to a decimal by using: >>> ...
I needed a function that simply checks if a string can be converted to a valid integer (for form validation). After searching around, I ended up using a function I had from 2002 which works using C#1 (below). However, it just seems to me that although the code below works, it is a misuse of try/catch to use it not to catch an error but...
I'm developing an app in C++/CLI and have a csv file writing library in unmanaged code that I want to use from the managed portion. So my function looks something like this: bool CSVWriter::Write(const char* stringToWrite); ...but I'm really struggling to convert my shiny System::String^ into something compatible. Basically I was hopi...
Is there a way to convert HTML into XAML? I noticed that you can paste HTML into a RichTextBox and you can get the XAML by looking at the FlowDocument. However, this is a hack. Is there a better way? ...
I'm trying to use XSLT text output to generate a file (in a file format that I'm not in control of), and while it is mostly text, it includes low-order non-printable characters as flags, including characters that are not valid within an XLST file (according to the XSLT specification). I'd like for something like the below to work, but i...
Hi there, I'm using Visual Studio 2005 and have a DataTable with two columns and some rows that I want to output to the console. I hoped there would be something like: DataTable results = MyMethod.GetResults(); Console.WriteLine (results.ToString()); What's the best way (i.e. least amount of coding from me) to convert a simple DataTa...
I have an oddly difficult task to perform. I thought it would be easy, but all my efforts have been fruitless. I'm converting videos uploaded to a php script from various formats (.avi, .mpg, .wmv, .mov, etc.) to a single .flv format. The conversion is working great but what I'm having trouble with is the resolution of the videos. Th...
Hi all :) I've got an USB card reader that I need to access from Lazarus / Delphi. The SDK is written in VB6 and talks to the serial port, so in Windows it installs a driver to map the USB port to a serial port. I'd like to skip that step (eg so that the same code works in Linux), but I'm not very familiar with the USB protocol, so I ...
Hi, there doesn't seem to be an existing util class for converting a storage unit from one to another in Java, am I right? Or is there one actually I wasn't aware of? What I was looking for is something like java.util.concurrent.TimeUnit utility. I can implement the equivalent for storage unit by myself, but just thought I would ask f...
Hi, I'm considering to add "hard" email verification to my website(s). I.e. require users visit a link with a verification key sent by email before they can post content. This will add an extra step in the registration procedure and I'm concerned that it may keep some users away. In practice how does this affect the rate of new people...
I have a single hexadecimal character, say char c = 'A'; What's the proper way of converting that to its integer value int value =??; assert(a == 10); Doesn't matter really for now if a is an int or a byte. ...
I don't think so, but I thought I'd ask just in case. For example, for use in a class that encapsulates an int: i = IntContainer(3) i + 5 And I'm not just interested in this int example, I was looking for something clean and general, not overriding every int and string method. Thanks, sunqiang. That's just what I wanted. I didn't ...
